Ok, in now for about a week. TLDR: fantastic. At least as bright as the HIDs and of course immediate response. Light pattern is good.
Mounting was a bit of a PIA. Because of the relatively large backside with the heatsink, and the horrific design in the ZOE headlight with the "click ring" instead of the more usual wire spring, you cannot fit the click ring. This was also a problem with the HIDs. The bulbs linked solve this with a mounting ring that is small enough to mount with the click ring into the headlight, then simply push in the bulb. It is held in place with 5 O-rings. It is a bit of a fiddly job, took me half an hour including carefully removing the HIDs, but doing it again would probably be 15 minutes. Most important thing to remember is: fit the mounting ring with the tube end facing the back of the car, then fix it with the click ring. Then simply press in the bulb. Done.

The click ring is tricky. The one coming from the car is fine, but mine were cut because of the HID mounting. There are real nice sturdy platic ones, but they can't stand the heat, stay away and use the flimsy steel ones. I don't have a UK/English link but this is what you need

My only beef with the setup is that the fan of one of the two lamps has a tiny imbalance, but when it gets warm and thus full speed there is this hum in the car. Not noticable while driving, but it is when parking. I am fairly sure it is a production problem if this single bulb; the other one does not have the issue. I have ordered another set for the old stinker. Assuming I am right, I will simply swap it, as that car is not driven at night that often.
Many thanks to Dutch forum user OlafH for the instructions. Pics here if you have an account:
